Question

a rectanglular feild is 48 m long and 40 m broad . if 1880 sq .m of field is already ploughed, how much field is yet to ploughed​

Answer 1

Answer:

area of rectangular field = l*b

where l is the length of field

b is the width of field

so area of field=48*40=1920 sq m ----eq1

already ploughed area= 1880 sq m ----eq2

so

area of field yet to be ploughed=1920-1880=40 sq m

Answer 2

Answer :-

• The field which is not ploughed is 40m².

Step-by-step explanation :

To Find :-

• How much field is not ploughed.

Solution :-

Given that,

• A Rectangular field is 48m long and 40m board.
• Field already ploughed = 1880m².

Formula used :-

Area of rectangle = l × b,

Where,

• l = Length
• b = Breadth

Therefore,

• Length of field = 48m
• Breadth of field = 40m

The area of Rectangular field is,

=> 48m² × 40m²

=> ( 48 × 40 ) m²

=> 1920 m²

Now, the field which is not ploughed is,

=> 1920m² - 1880m²

=> ( 1920 - 1880 ) m²

=> 40m²

• The field which is not ploughed is 40m².
